Compute the magnitude of the following vectors:
`veca = hati+hatj+hatk,vecb = 3hati+hatj-4hatk,vecc= - 1/sqrt3hati-1/sqrt3hatj+1/sqrt3hatk.`

Find the sum of the vectors veca = -2hati+hatj-4hatk and vecb = 3hati-hatj+5hatk .

Write down the magnitude of each of the following vectors : (i) veca = hati + 2hatj + 5hatk , (ii) vecb = 5hati - 4hatj - 3hatk (iii) vecc = (1/(sqrt(3))hati - (1)/(sqrt(3)) hatj + 1/(sqrt(3))hatk) , (iv) vecd = (sqrt(2)hati + sqrt(3)hatj - sqrt(5) hatk)

Obtain the magnitude of 2vecA - 3vecB if vecA = hati + hatj - 2hatk and B = 2hati - hatj + hatk .

If veca = 2 hati - 3hatj, vecb = hati + hatj -hatk, vecc = 3hati - hatk, find [a vecb vecc]

Find vecB xx vecA if vecA = 3hati - 2hatj + 6hatk and vecB = hati - hatj + hatk .

Find the projection of vector veca=5hati-hatj-3hatk on the vector vecb=hati+hatj+hatk .

Find the projection of the vector veca=3hati+2hatj-4hatk on the vector vecb=hati+2hatj+hatk .
